Question

What gets printed by the code snippet below?
import math
print math.floor(5.5)

Answer 1

Output of the code snippet is 5

Explanation:

• The Math.floor() returns the largest (closest to positive infinity) double value that is equal to or less than the argument and represents a numerical integer. If the value of the argument is already equal to a numerical integer, then the result is equivalent to the argument. When the argument is either infinity or positive zero or negative zero, the result is the same as the argument.
• So as per the functionality, closest to positive less than or equal value for the given code will be 5.

Answer 2

Returns the largest integer value either equal to the given number or less than the given number

Explanation:

import math : This statement will import the math library. The math library will contain the commonly used functions to perform round off operation, find the square root, etc. The floor() is available in math library / header file.

print math.floor(5.5)

This would return "5" by truncating the decimal value. In other words it returns integer value from the given decimal value. The integer would either be equal or less than the given number.
